How do you solve it and how do you explain?

so the answer is 30

now to find the answer we just need to do this...

step 1: we need to simplify the equations from both sides.

then we multiply on both sides by

which equals x= 30

Step-by-step explanation:

hope this helps!!

well the 1 and -1 are always after the 0 and the 0 is inthe middle. s thats what i would guess. but i dont know what a slope of 2 is sorry

step-by-step explanation:

it has the same slope and a different y-intercept

hope this : )
